Oil prices have fallen 20% from their 2026 peak because the US and Iran appear close to a ceasefire deal. If the Strait of Hormuz — the world's most important oil shipping route — reopens, a lot of trapped oil supply could flood back into the market.

## Idea

The Strait of Hormuz has been shut since the Iran war started in February, choking off roughly 20% of the world's daily oil supply and sending prices sky-high. Now President Trump says a 'final determination' on a deal is imminent, and oil has already dropped 20% from its peak on that hope alone. But here's the key: the strait isn't open yet. If and when a deal is formally signed and tankers actually start moving through again, the sudden return of all that supply could push prices down even further. Oil stocks in the energy sector ETF (XLE) would feel the squeeze too, since their profits are tightly linked to the price of crude.
